' 8 Claims.

, This invention relates to spinning and twisting rings. When referencehereinafter-ismade :tola spinning ring, it is to be understood-that theexpression includes'as well twisting rings.

The invention is particularly concerned with that type of spinning ringmade .of powdered metal. Powdered metalrings have recently come intoextensive use because-of the-ease with-which they may be kept properlylubricated; thereby to lengthen greatly the life ofthe traveler as itmoves at high velocity about the ring.

One of the difficulties encountered =in--the;-.use of powdered metalspinning rings is the .question of feeding oil to the ring at theproper, rate. .The ring and its supporting flange,- beinggporous,absorbsthe oil as received transmitting-it to the entire circumferentialsurface of the ring "from which it is picked up ,by the traveler. Ifoil-is received by the ring at too great-a rate, the traveler cannotutilize all that is:availablewith :the result that some of the oil willcollect onthe exterior portions of the ring thatare notengaged by thetraveler and on these oily .-areas, lint and 'dirt will gather inanobjectionable manner.

It hasbeen found that it is :better .to control the rate of oil fedtothe spinning ringthanto vary the structure of the ring itself to make itmore or less absorbent. In other wordsyit is better to'havea ring ofstandardabsorptive capacity-and then feed oil to it at the appropriaterate. to'meet the'required lubrication conditions.

-Accordingly, it .is an object of this invention. to provide means whichmay be used-with-conventional individual spinning rings and theirholders which will result inthe oil being transferred to the ring properat-whatever rate, is required. The invention: is such that if the .rate'of oil feeding is found to be too high, modification of. the meter- 'ingmeans may :be made to decrease .the rate of absorption and conversely,if .the rate of feed is found to be too low to provide properlubrication, the metering means again. may: bevaried so that the rate ofabsorption maybe increased.

, Another object of the, inventioneisto .provide a spinning ring oilsupplying.- mechanism havinga reservoir. in which a supply of oil may be.placed sufficient to last for a substantialcperiod of time the oilbeing transmitteditothe rings-at: a-;sloW metered rate.

A further object of the invention is to provide :a construction for'feecling oil at ametered rate to either the horizontal type of spinningring, or the vertical type. That :is t'ozsay,rtheYbasestructure which.support the: spinningring .an'd the metering mechanism can bemade-isubstantially 2 identical regardless of the particular type of rinthat is-attac'hed, thereto.

These and. other objects of the invention will become .moreapparent asthe description proceeds with the aid of the accompanying drawings, inwhich Fig. 1 is a plan view of a spinning ring mounted on a holder whichincorporates the invention.

Fig. -5' is a fragmentary plan view of the front half of a spinning ringholder similar to that shown in Fig. 3, but with the width-of thechannel reduced at the front'thereof tofacilitate piecing up by theoperator.

Fig. 6 is a vertical sectional view similar to Fig. 2, but showing theinvention in use with a vertical type spinning ring rather than thehorizontal type of Fig. 2.

Fig. 7 is an enlarged fragmentary plan view of the ends of the wickcarrying separator.

Fig. 8 "is a side elevation on the line 8-8 of Fig. 1 showing inenlarged detail the metering mechanism and ring.

Referring to Fig. 1, there is shown a ring rail .2 on which is mountedin a conventional manner a spinning ring holder 4. This holder hastypical feed 6 andtenabling the ring to be secured to the railby thescrews [0 and I2.

As can be, seen in Fig. 2, which is a vertical section taken on the line2-4 of Fig. l, the holder 4 includes a circular channel or moat l4 aboutthe bottom of which oil flows as itLmay be received from the reservoir16 which has a passage I 8 leading therefrom into the channel l4.

Extending about the channel M as shown in Fig. 4 are aplurality ofstaggered lugs 20 which 'act to support a wick carrying separator 22which can be seen in Figs. 2 and 3. This separator is not continuous,but is broken with its ends at 24 and 26. As can be seen in Figs. 2, 3,4, and 8, the metering meansconsists of a short length of felt 28 with:itsrends atSll and 32 positioned in the channel M where it willunderlie the end portions of separator 22. The length and :density-ofthis metering felt may be varied to give it greater or less oilabsorbing and transmitting capacity.

.1'Ihe1upper'surface of separator 22 has a depres- .sion;34 in iwhich-islaid; for, the;=entire circumference thereof a wick 36 preferably madeof fine filaments of glass, braided together to form what is known as aglass wick. Glass wicks are commercially available and use is madethereof because they constitute the most suitable type of wick nowknown.

The two ends 24 and 26 of separator 22 are notched as at 38 and 40 inFigs. 7 and 8. These notches are helpful in maintaining wick 36 inposition in depression 34 as the unit is being assembled and assist inholding the ends 32 and M of wick 36 as shown in Fig. 8 in properposition against the metering felt 28.

After the separator 22 and the wick 36 mounted thereon have beenassembled to the position shown in Fig. 3 with separator 22 supported bylugs 20 and with the wick ends 52 and 44 resting on the metering felt28, the spinning ring proper may then be inserted in the holder. Thisarrangement is shown in Fig. 2 in which the oil receiving flange 45 ofthe ring 41 is of such vertical dimension that when the shoulder 4-8 isresting on the upper edge 50 of the inner wall 52 of the channel M, thebottom 54 of flange 46 will rest on top of and make good contact withwick 36 about the latters entire circumference with the exception of theshort section between the ends 24 and 26 of separator 22. This shortomission, however, is insufficient to cause any adverse eifect to theoil transmission. The ring 41 is secured to the holder by screws 55.

With the unit assembled in the manner just described, oil is then placedin reservoir it from which it flows through passage 18 and around thebottom of the channel It. In due course, the oil reaches and saturatesmetering felt 28, which is positioned approximately 180 from the passageit so that oil will reach it simultaneously from both sides.

Metering felt 28 now saturated with oil then begins to transmit the oilto the ends t2 and 44 of wick 36 with the result that the oil is thencarried about the entire circumference of the wick as it rests in theshallow channel 34 of the upper side of separator 22. Inasmuch as thebottom of flange 46 is resting on wick 36, it is obvious that oil willin this way begin to be transferred to the underside of flange 46,thence, oil will move upwardly through the vertical rib 56 into ring 41.about its entire circumference by wick 36, it will be understood thatthe absorbed oil will arrive at all parts of ring M substantiallysimultaneously. Feeding that occurs thereafter will likewise be uniformso that the traveler 60 will be properly lubricated at all portions ofthe ring 41 as it moves thereabout.

The above described construction has the great advantage that the rateat which ring 4'! receives oil may be varied at will. In the firstplace, the metering felt may be changed to more or less absorbentmaterial so that the rate of feed to the wick ends 42 and 44 may bevaried. Again, the size and character of wick 35 may be varied so thatthe under side of flange 46 will be presented with more or less oil asconditions require. In other words, the surface contact between wick 36and the under side 54 of flange "it may be changed and thus the totalamount of oil entering the ring 58 may be directly controlled. In thisway, if it is found that the traveler 6D is receiving too much or toolittle oil, the wicks may be shifted to correct the condition. When theproper balance is reached, no fur- Since oil is being fed to flange atther attention to the oiling system is required,

except the occasional addition of oil to reservoir l6.

It should be noted that the inner and outer perimeters of separator 22make a very close fit with the inner and outer walls of channel Hi.Thus, even though the space between the under side of separator 22 andthe bottom of channel M is completely filled with oil, no oil will bereceived by wick 36 except that which is introduced from metering felt28 to the wick ends 42 and 44. Accordingly, with the reservoir availablefor oil storage plus the substantial circumferential space beneath theseparator 22, there is available enough oil to last for an extendedperiod.

The construction shown in Fig. 6 with respect to the metered oiltransferring characteristics of the invention is the same as that shownin Fig. 2. The difierence, however, resides in the fact that the ring4'! has been replaced by a vertical type ring 60, which is connected tothe flange 46 in the manner shown. This has necessitated shortening thevertical dimension of the inner wall 62 of the channel, but does notaffect the construction of the oil separator 22, the metering felt 28 orthe wick 36.

The construction illustrated in Fig. 5 is included to show that theinvention may be used with equal facility with that type of ring andholder in which the oil channel is narrowed in front so that theoperator may get his finger in closer under the outer portion of ring 41when piecing-up. In this construction, the separator 22 is cut awayalong its outer edge at the appropriate place to fit within the narrowedchannel between the inner wall 6t and outer wall iii: of the holder.This change in form does not, however, affect transfer of oil to thebottom of the ring flange it; for the wick 3G is continuous about theholder base the same as in Fig. 3.

The term metering felt as used herein is not to be construed as limitingthe metering mechanism to the use of material made of animal fibers;rather the term is intended to mean any suitable material capable ofacting in the manner described so as to absorb oil in the channel and totransmit the oil to the wick which is in contact therewith.

It is my intention to cover all changes and modifications of the exampleof the invention herein chosen for purposes of the disclosures which donot constitute departures from the spirit and scope of the invention.
